Application filed July 2a, 1923. Serial No. 654,422.

' To all whom it may concern:

Be it known that I, VVILLIAM H. LovELjAon, a citizen of the United States, residing at Dalna, in the countyv of Letcher and State of Kentucky, have invented new anduseful Improvements in Holders, of which the following is a specification.

This invention has reference to. electric arc Welding, and is particularly directed to an electrode holder.

An important object is to produce a holder for this purpose which will quickly grip and likewise quickly release an electrode and thus obviate theneccssity of cutting off the current as is true with the ordinary class of electrode holders when the electrode is engaged thereby or released therefrom.

A further object is to produce'an electrode holder for electric'arc welding in which the outer end thereof is protected by. an insulator to obviate the liability of damaging the holder when the end thereof is brought in contact with .a surface of electric conductivity, such as is apt to occur when the welding operation takes place in close quarters.

The foregoing, and many other objects which will present themselves as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts such as is disclosed by the drawin which accompany and which form part 0 this application.

In the drawings r y Figure 1- is a' general view of the improve ment. 1

. Figure 2 is a sectional view approximately on the line 2-2 of Figure 1. I j

Figure 3 is a sectional view approximately on the line 3-3 of Figure 1.

Figure 4 is a perspective view showing the apertured block that provides the holder for the electrodes.

- Figure 5 is a perspective view of the notched end. ofthe slidable tubular member.

Figure 6 is a perspective View of the handle.

Referring now to the drawings in detail,

the numeral 1. designates the handle portion of my improvement. The handleis preferably'in the nature of a hollow tube of in-- sulating material and has on its'outer end a disk-like guard 2 of similar materialf Pass- .ing through the hollow handle, but secured thereto there is a metalv tube 3. In one .end of this tube there are clamped the conductors.

The portion of the tube which projects beyond the guard has diametrically opposed elliptical openings 4 therethrough arranged adjacent to the outer end of the said tube. This end of the tube is surrounded by a sleeve of insulating material 5 which is provided with elliptical openings that align with the openings 4.

In the tube 3 there is a slidable member 6. The member 6 has on its inner end a disk 7 of insulating material. and contacting with this disk and a suitable stop 8 in the tube 3 there is a helical'spring 9. The spring project's the member 6 toward the outer end of .the tube. and the outer end of the said memher 6 is formed with a V-shaped notch to provide opposed angle jaws 10, and these jaws are normally forced by the spring beyond the openings 4-in the tube and in the insulating sleeve.

Having one end passing through a slot in the tube, just outward of the guard 2 there is the straight end 11 of a handle. The end 11 also enters a notch 12 in the slidable jaw carrying member 6. At the sides of the opening in the tube 3 through which the end 11 of the handle passes there are outstanding-ears 13, the said end being pivoted between-the ears, as at 1 1. The straight end 11 outward of the ears 13, is bent angularly andis thence continued at a curvature through an arcuate slot 15 in the guard 2. The rounded end of the handle, indicated by the numeral 16 has a coverng of insulating material 17. I

- To facilitate the arrangement of electrodes in the holder, I provide a block 18 that has on its upper face series of apertures each of a size to receive therein one end of an electrode 19. The apertures are so spaced that the outer end of the holder may be 2.1-

ranged over any of the electrodes to permit of the same being passed through the openings in the end of the holder. In this operation the insulated active end of the handle The quick release of the electrode is a very desirable feature in the art to which this invention relates, as speed is an essential element in successful welding, and should the parts to be welded become cold, the metal will not properly fuse. In addition to this,it has been often found that the electrode will stick to the piece being welded and cause damage to the coils in the welder. With my quick release this will be obviated. and it is thought that the foregoing description when taken in connection with the drawings will fully set forth the construction and ad vantages of the improvement. It is to be stated, however, that I do not desire being restricted to the precise illustrative embodiment herein disclosed but hold myself entitled to such changes therefrom as fall withinthe scope of what I claim. I

Having described the invention, I claim 1. In arc welding, an electrode holder including a handle of insulating material ha ving a guard at its outer end, a hollow mem-' ber passing through and secured to the handle and to which the electric conductors are attached, said member having aligning openings adjacent to its outer end, a sleeve of insulating material surrounding the said end of the member and having openings therethrough registering with the first men-i tioned openings, a spring influenced jaw carrying element slidable throu h the member normally covering the openings, a handle for retracting the member against the pressure of its spring, said handle comprising a pivoted member having its active end of insulating material and which is directed toward the handle.

2. In electric arc welding, a holder for electrodes. comprising a handle of insulat ing material having a slotted guard of similar material at its outer end, a hollow metal member passing through and secured to the handle and to which the'ele'ctrie conductors are connected, said member having aligning elliptical slots adjacent to its outer end, a sleeve of insulating material having similar slots on said outer end, a slidable aw carrying element in said member, and having an inner end of insulating material, a helical spring in the member contacting said end for moving the element to bring itsjaws'to cover the mentioned openings, a handle pivotally secured to the member and having an end received in a slot in the slidable element, and said handle having an outer curved end of insulating material which is received through the slot in the guard.

In testimony whereof I affix my signature.

WILLIAM H. LOVELACE.
